 Title: ATOMIC AND MOLECULAR SPECTRA OF XENON, KRYPTON, AND ARGON IN THE VACUUM ULTRAVIOLET. Creators: Wilkinson, P. G.; Hulburt, E. O. Issue Date: 1965 Publisher: Ohio State University Abstract: Lifetimes of the lowest $^{1}P^{0}_{1}$ and $^{3}P^{0}_{1}$ states of Xe and Kr have been measured by a photoabsorption technique. The results give for Kr: $\tau(^{1}P^{0}_{1}) = 4.55\cdot 10^{-9}$ sec and $\tau(^{3}P_{1}^{0}) = 4.38 \cdot 10^{-9}$ sec; for Xe. $\tau(^{1}P^{0}_{1}) = 2.80 \cdot 10^{-9}$ sec and $\tau(^{3}P^{0}_{1}) = 3.74 \cdot 10^{-9}$ sec. The lifetimes of the metastable $^{3}P^{0}_{0}$ and $^{3}P^{0}_{2}$ states, while not explicitly measured here, are shown to be longer than the non-metastable states and play important roles in the continuous emission spectra of rare gas molecules in the vacuum ultraviolet. Laboratory measurements of the emission intensity $(I_{em})$ of the argon molecular continuum as a function of pressure $(PA_{r})$ show that $I_{em}^{1/2}/PA_{r}$ is a linear function of argon pressure. A mechanism is proposed which accounts for the experimental observations. Sponsored jointly by the Office of Naval Research and the National Science Foundation.
